In my opinion it is best to announce something when it is actually done. For example, if I were to say that I am building a website and it will be available soon, that would just create a hype or price speculation. I'd rather go for the "here is the website" and let everything else takes its own path. So on behalf of communication I hope that something will be announced when it is done and not at a possibly maybe go live stage where the risk of not delivering on time will do more damage in this crypto world.
So from my perspective, it is done when it is done and i'll just wait patiently to see what will be announced.
